Forms

Etymology

It is inherited from Proto-Indo-European *kr̥tús, from the root *kret-.[1] It is the zero-grade adjective of the family of κράτος (krátos, “strength, power”), whose old full grade survives in Aeolic κρέτος (krétos); the same alternation is seen in βαθύς (bathús) beside βένθος (bénthos).[2][3][4] Risch derived κραταιός (krataiós) from an old feminine of κρατύς.[2][4]

No exact match to the family is found in the other Indo-European languages.[2] The closest are Sanskrit क्रतु (krátu, “power, mind, will”) and, as Frisk adds, Old English cræft (“strength, power, skill”); the Germanic word for “hard” (heard) is often connected, though its vowel differs.[2][3][1] Pokorny puts the family under a root *kar- (“hard”).[5]

Earliest recorded meaning

It is found only in Homer and the Homeric Hymns, always in the line-end formula κρατὺς Ἀργειφόντης (kratùs Argeiphóntēs, “the mighty Argeiphontes”), an epithet of Hermes (Il. 16.181, 24.345, Od. 5.49).[6][7][8][2]

Semantic evolution

Cunliffe and Autenrieth treat it as an equivalent of κρατερός (kraterós) “strong, mighty”, and Pape notes that only the nominative occurs.[8][9][10] Hesychius glosses it with κρατερός and ἰσχυρός, “strong”.[11] Its derivative κρατύνω (kratū́nō) “to strengthen, consolidate, rule” is found from the Iliad on, with later nouns such as κρατυσμός (kratusmós) “strengthening”.[2][3]

Timeline

  • Homer – The Iliad and the Odyssey use it in the formula “mighty Argeiphontes”, of Hermes.[8][6]
  • 7th century BC – The Homeric Hymn to Aphrodite repeats the formula.[12][7]
  • 5th century AD (probably) – Hesychius glosses it as “strong”.[11][13]
